Greybull is a ways north of Worland, and like Worland and Thermopolis, is situated on the banks of the Big Horn River.
THE MODEL RAILROAD
The track in Greybull:
North is to the right in this diagram. Off the left end (south) is the line that skirts the helix and winds up in Basin. Traveling off the right of the diagram leads to Lovell.
I know next to nothing about the railroad's activities in Greybull - it will be fun to research what industries were served, and how much the railroad influenced life in this interesting little berg. The current major railroad-related industry is bentonite mining.
